Monitoring system of sewerage treatment based on wireless network

How to protect the fresh water sources is one of the principal problems in the human society, and obviously the industrial sewerage is the main pollution source. However, some water quality monitoring systems based on WSN have been done; we found that the traditional WSN nods have a disadvantage of short-distance communication among the nods, which limits the application in monitoring the industrial sewerage. In this paper, we describe a new monitoring system, which is based on the ZigBee network, the RF front circuit and the dynamic routing, in order to realize long-distance communication among the nods and real-time monitoring. This system described is general, extensible, self-organized and adaptive, with large area overlay and excellent compatibility.
